At the end of this note I describe how InnoDB can be much faster (2.5X) for high-concurrency workloads. However, what we really did is improve the code to not get 2.5X slower. InnoDB uses innodb_thread_concurrency to limit the number of threads that run concurrently...
InnoDB uses background threads to handle readahead (prefetch) requests. Requests are generated when it detects sequential or random access to most blocks in an extent. This is described in the 5.0 MySQL manual with new behavior in the plugin...

Innovative thinking at Facebook isn't only about software.
With Facebook users spending a collective 8 billion minutes on the site each day, serving 1.2 million photos each second, and managing more than 25 terabytes of data per day in logging data, we're forced to think about servers and datacenters differently.
Amir Mi...chael, a server and datacenter engineer at Facebook, explains how thinking differently can lead to significant gains in cost and energy efficiency.Read More

We have servers that run with innodb_log_file_size=256M and some of these servers do a lot of disk writes per second...

Apache Hive is a data warehouse built on top of Apache Hadoop, that provides tools to enable easy data summarization, adhoc querying and analysis of large datasets data stored in Hadoop files. It provides ...
I was debugging a server that had too many concurrent queries. From SHOW INNODB STATUS output, there were many long running transactions with uncommitted work and there were many more transactions blocked on InnoDB locks...
As you might be aware, one of Facebook's oldest and greatest traditions is the Hackathon. Every few months, our engineers decide to stay up all night and just build it...

Hello. I'm Ryan Mack, a new member of the Facebook MySQL team. My first order of business is evaluating MySQL 5.1 and the new InnoDB plugin. So far things look very promising, but I came across one issue worth sharing...

Mike Schroepfer (Facebook), "High Order Bit: The Infrastructure of Facebook"
Facebook Engineering "We move as fast as we can to launch things quickly and then iterate to make them better. We would rather take risks and break a few things in the process than move slowly. It's not unusual for the code someone writes one day to be in use by hundreds of millions of users that same night."

"We are growing aggressively but we want to grow carefully. The quality of the people and the efficiency is critical to Facebook. Metric that we track is how many eng to how many users – north of one million to one for some time. This is 10-30x any other tech company. If you look at our projects where other compani...es have say 20-30 engineers Facebook has 2 or 3. It’s very efficient model for Facebook. Teams are peaked around the core distributed platform for rapid development."Read More
